Ethernet Interface - Analog Devices EZ-Board ADSP-BF518F Manual

Ethernet Interface

If the processor pins are needed for the expansion interface II, disconnect
the rotary encoder switch via the three-position rotary enable switch
( ). For more information, see "Encoder Enable Switch (SW19)" on
SW19
page 2-14.
An example program is included in the EZ-Board installation directory to
demonstrate how to set up and access the rotary encoder interface.
Ethernet Interface
The ADSP-BF518F processor has an integrated Ethernet MAC with
media independent interface (MII) which connects to an external PHY.
The EZ-Board provides a Micrel KSZ8893M Integrated 3-Port 10/100
Managed Switch with PHYs, fully compliant with IEEE 802.3u standards.
The KSZ8893M chip supports 10BASE-T and 100BASE-TX operations.
The part is attached gluelessly to the processor.
The Ethernet signals are shared with the PPI signals connected to the
expansion interface II.
The Ethernet mode is set by three switches. Switch

The Ethernet chip is pre-loaded with a MAC address. The MAC address
for the EZ-Board is stored in the configuration flash section of the parallel
flash memory and can be found on a sticker on the bottom side of the
board.
